A nurse is reviewing the diagnostic test results of a female client who is about to undergo knee arthroplasty. Which of the following data collection findings should the nurse identify as the priority?

Creatinine 0.9 mg/dL

WBC count 20,000/mm3

Potassium 3.8 mEq/L

Hematocrit 40%

Answer and Explanation

The Correct Answer is B

a. Creatinine 0.9 mg/dL: This creatinine level is within the normal range and is not an immediate priority for knee arthroplasty.

b. WBC count 20,000/mm3: An elevated white blood cell count suggests the presence of

infection or inflammation. In the context of knee arthroplasty, infection is a significant concern and requires immediate attention to prevent complications.

c. Potassium 3.8 mEq/L: This potassium level is within the normal range and is not an immediate priority for knee arthroplasty.

d. Hematocrit 40%: This hematocrit level is within the normal range and is not an immediate priority for knee arthroplasty. The elevated WBC count takes precedence as it suggests a

potential infectious process.

Correct Answer is C

Explanation

a. Allow the client to take her morning vitamins: This is generally acceptable unless there are specific preoperative instructions regarding medication.

b. Allow the client to keep her tongue stud in: Metallic objects, including tongue studs, are

usually removed before surgery to prevent interference with equipment and to ensure patient safety.

c. Allow the client to keep her hearing aids in: It is important for the client with a hearing

impairment to keep hearing aids in place to facilitate communication and maintain awareness of the environment.

d. Allow the client to consume clear liquids up to the time of surgery: Clear liquids are typically restricted before surgery to prevent aspiration. This action may not align with standard

preoperative fasting guidelines.

A. Serum potassium B. Serum amylase C. Serum triglyceride D. Serum cholesterol

Correct Answer is A

Explanation

a. Serum potassium: Furosemide is a loop diuretic that can lead to potassium loss, potentially causing hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias.

b. Serum amylase: This is not directly related to furosemide therapy. Amylase is an enzyme associated with pancreatic and salivary function.

c. Serum triglyceride: Furosemide does not typically have a direct impact on serum triglyceride levels.

d. Serum cholesterol: Furosemide does not typically have a direct impact on serum cholesterol levels.
